Dr. Burke performs an experiment to determine how plants grow in a variety of temperature and moisture conditions. He runs five
trials with five different groups of the same species of plant. The table below shows the results from his experiment.
Plant Group Temperature Moisture Average Plant Growth
Group 1 high
high 2 in
Group 2 moderate moderate 6 in
Group 3 low
low
Group 4 high moderate 3 in
Group 5 moderate high
O in
After finishing the experiment, Dr. Burke explains that heat and moisture have no effect on plant growth. Based on the evidence
shown in the table, is his explanation valid?
A. No, the evidence shown in the table does not support his explanation
B. Yes, his experiment is well designed so his results do not need to support his explanation
C. Yes, the evidence shown in the table supports his explanation.
D. No, he did not test plants in moderate moisture and moderate temperature conditions.
